Finte

Finte is a proc-macro crate to auto generate conversion code between integer and Rust enum

Example

```rust

[derive(finte::IntEnum)]

[repr(u16)]

pub enum RustEdition { Prev = 2015, Now = 2018, Next = 2021, }

// the above generates

impl finte::IntEnum for RustEdition { type Int = u16;

fn try_from_int(value: Self::Int) -> Option<Self> {
    match value {
        2015 => Some(Self::Prev),
        2018 => Some(Self::Now),
        2021 => Some(Self::Next),
        _ => None,
    }
}

fn int_value(&self) -> Self::Int {
    match self {
        Self::Prev => 2015,
        Self::Now  => 2018,
        Self::Next => 2021,
    }
}

} ```
